 The old configuration file, contained in the API Route (`pages/api/auth/[...nextauth].ts` / `app/api/auth/[...nextauth]/route.ts`), now becomes much shorter. **These exports are designed to be used in an App Router API Route**, but the rest of your app can stay in the Pages Router if you are gradually migrating!

 The above is an example. The takeaway is to separate the part of the configuration that is edge-compatible from the rest, and only import that in Middleware/Edge pages/routes.
